Is it possible to enter a dynamic value for model in "Extract information from forms"

[Lucian]

Hello,

I am evaluating how can I use AI Builder to extract information from invoices sent to a specific mailbox. Because I'm not in US I cannot use the "prebuilt" model and I have to use the custom model.

Also because of the model requirements and limitations to maximum 200 collections, I might have to build 2 or even 3 models and depending on the sender to process the information with the right model.

To test the idea, I have created 2 models and using an switch action card I could test which of my two demo email addresses is the sender and on the each case branch I will use the proper model and everything seems fine.

But I want to improve this flow, and instead of using the "Extract information from forms" on each case, I prefer on that switch action just to determine which model should be used and after that call the proper model.

The problem is that I cannot use the dynamic variable in the "AI model" field. If I use the name of the variable that contains the GUID of the model, I cannot save the flow because of an error:

"Flow save failed with code 'OpenApiOperationParameterValidationFailed' and message 'Input parameter 'item' validation failed in workflow operation 'Extract_information_from_forms': The API operation 'PredictV2' is missing required property 'item'.'."

But if I manually enter the same GUID will work, and after closing and re-opening the flow will use the name of the model as if I chosen it from the dropdown list.

So, is there a way to use a model by its ID, using a dynamic value?

Or I have to use the "Extract information from forms" action inside each case branch of the switch?

Kind Regards,

Lucian

Hi @Lucian ,

It seems that you can use that documentation to solve your use case: Use predict action in Power Automate - AI Builder | Microsoft Docs

Hope that helps.

Hi @Antrod ,

Indeed that did the trick. Thank you very much for pointing me to the right track and the link with the documentation.

Hi. how you resolve this question?

Hi @TET1 ,

Basically, the instructions in the documentation provided by @Antrod , using the "Predict" action will let you dynamically use the model ID to extract the data.

In my case, I just organize 3 models, so using the "From" field of the email I will "know" which model ID I should use, then instead of using "Extract information from forms" action for each model just to see which will return "something", I use "Predict" action with the proper model ID that is "dynamic".

Kind Regards,
